BACKGROUND Technical Field

The present invention relates to a compound for an organic electronic element, an organic electronic element using the same, and an electronic device thereof.

Background Art

In general, organic light emitting phenomenon refers to a phenomenon that converts electric energy into light energy by using an organic material. An organic electronic element using an organic light emitting phenomenon usually has a structure including an anode, a cathode, and an organic material layer interposed therebetween. Here, in order to increase the efficiency and stability of the organic electronic element, the organic material layer is often composed of a multi-layered structure composed of different materials, and for example, may include a hole injection layer, a hole transport layer, an emitting layer, an electron transport layer, an electron injection layer and the like.

A material used as an organic material layer in an organic electronic element may be classified into a light emitting material and a charge transport material, such as a hole injection material, a hole transport material, an electron transport material, an electron injection material and the like depending on its function. And the light emitting material can be classified into a high molecular weight type and a low molecular weight type according to the molecular weight, and according to the light emission mechanism, it can be classified into a fluorescent material derived from a singlet excited state of an electron and a phosphorescent material derived from a triplet excited state of an electron. Also, the light emitting material may be divided into blue, green, and red light emitting materials and yellow and orange light emitting materials necessary for realizing a better natural color according to the emission color.

However, when only one material is used as a light emitting material, due to intermolecular interaction, the maximum emission wavelength shifts to a longer wavelength, and there are problems in that the color purity is lowered or the device efficiency is reduced due to the emission attenuation effect, therefore in order to increase color purity and increase luminous efficiency through energy transfer, a host/dopant system may be used as a light emitting material. The principle is that when a small amount of a dopant having a smaller energy band gap than that of the host forming the emitting layer is mixed in the emitting layer, excitons generated in the emitting layer are transported to the dopant to emit light with high efficiency. At this time, since the wavelength of the host moves to the wavelength band of the dopant, light having a desired wavelength can be obtained according to the type of dopant used.

Currently, the portable display market is a large-area display, and the size thereof is increasing, and thus, more power consumption than the power consumption required for the existing portable display is required. Therefore, power consumption has become a very important factor for a portable display having a limited power supply such as a battery, and the problem of efficiency and lifespan must also be solved.

Efficiency, lifespan, and driving voltage are related to each other, and when the efficiency is increased, the driving voltage is relatively decreased, and as the driving voltage is decreased, crystallization of organic materials due to Joule heating generated during driving decreases, and consequently, the lifespan tends to increase. However, the efficiency cannot be maximized simply by improving the organic material layer. This is because, when the energy level and T1 value between each organic material layer, and the intrinsic properties (mobility, interfacial properties, etc.) of materials are optimally combined, long lifespan and high efficiency can be achieved at the same time.

Therefore, while delaying the penetration and diffusion of metal oxide from the anode electrode (ITO) into the organic layer, which is one of the causes of shortening the lifespan of the organic electronic element, it should have stable characteristics against Joule heating generated during device driving, and OLED devices are mainly formed by a deposition method, and it is necessary to develop a material that can withstand a long time during deposition, that is, a material with strong heat resistance.

In other words, in order to fully exhibit the excellent characteristics of an organic electronic element, it should be preceded that the material constituting the organic material layer in the device, such as a hole injection material, a hole transport material, a light emitting material, an electron transport material, an electron injection material, etc., is supported by a stable and efficient material. But the development of a stable and efficient organic material layer material for an organic electronic device has not yet been sufficiently made. Therefore, the development of new materials is continuously required, and in particular, the development of a host material for the emitting layer is urgently required.

Referring to FIG. 3 , in the organic electronic element (300) according to another embodiment of the present invention, 2 or more sets of stacks (ST1 and ST2) made of a multi-layered organic material layer may be formed between the first electrode (110) and the second electrode (170), and a charge generation layer (CGL) may be formed between the stacks of organic material layers.

Specifically, the organic electronic element according to an embodiment of the present invention includes a first electrode (110), a first stack (ST1), a charge generation layer (CGL), a second stack (ST2), and a second electrode. (170) and a light efficiency enhancing layer (180) may be included.

The RE value of the compound represented by Formula (1) is preferably 0.21 to 0.298, more preferably 0.22 to 0.293.

Reorganization Energy refers to energy lost due to changes in molecular structure arrangement when electric charges (electrons, holes) move. It depends on the Molecular geometry, and the smaller the difference between the PES (Potential Energy Surface) in the neutral state and the PES in the charge state, the smaller the value becomes. RE value can be obtained by the following formula. RE_(hole):λ⁺=(E _(NOCE) −E _(COCE))+(E _(CONE) −E _(NONE)) RE_(elec):λ⁻=(E _(NOAE) −E _(AOAE))+(E _(AONE) −E _(NONE)) Each factor is described as NONE: Neutral geometry of neutral molecules (=NO opt.), NOAE: Anion geometry of neutral molecules, NOCE: Cation geometry of neutral molecules, AONE: Neutral geometry of anion molecule, AOAE: Anion, anion geometry of molecules (=AO opt.), CONE: Neutral geometry of cation molecules, COCE: Cation geometry of cation molecules (=CO opt.)

Reorganization Energy value and mobility are in inverse proportion to each other, and under the condition that they have the same r and T values, RE value of each material directly affects the mobility. The relation between RE value and mobility is expressed as follows.

$\begin{matrix} {\mu = {k\frac{r^{2}}{2k_{B}T/e}}} \\ {k = {\left( \frac{4\pi^{2}}{h} \right)\frac{t^{2}}{\sqrt{4\pi\lambda k_{B}T}}{\exp\left\lbrack {- \frac{\lambda}{4k_{B}T}} \right\rbrack}}} \end{matrix}$

Each factor is described as λ: Reorganization energy/μ: mobility/r: dimer displacement/t: intermolecular charge transfer matrix element. From the above equation, it can be seen that the lower RE value, the faster the mobility.

Reorganization energy value requires a simulation tool that ca Calculate the potential energy according to the molecular structure, we used Gaussian09 (hereinafter G09) and Jaguar module of Schrodinger Materials Science (hereinafter JG). Both G09 and JG are tools to analyze the properties of molecules through quantum mechanical (QM) calculations, and have the function of optimizing the molecular structure or calculating the energy for a given molecular structure (single-point energy).

The process of performing QM calculations in molecular structures requires large computational resources, and our company uses 2 cluster servers for these calculations. Each cluster server consists of 4 node workstations and 1 master workstation, each node performed molecular QM calculations by Parallel computing through symmetric multi-processing (SMP) using a CPU with more than 36 cores.

Using G09, the optimized molecular structure and its potential energy (NONE/COCE) in the neutral/charged state required for rearrangement energy were calculated. The charge state potential energy (NOCE) of the structure optimized for the neutral state and the neutral state potential energy (CONE) of the structure optimized for the charge state were calculated by changing only the charges to the 2 optimized structures. After that, the rearrangement energy was calculated according to the following relation. RE_(charge):λ=(E _(NOCE) −E _(COCE))+(E _(CONE) −E _(NONE)) Because Schrödinger provides a function to automatically perform such a calculation process, the potential energy according to each state was sequentially calculated through the JG module by providing the molecular structure (NO) of the basic state, and the RE value was calculated.

According to an embodiment of the present invention, more electrons are attracted to an element having a greater electronegativity among two atoms in one covalent bond.

Here, the relatively high electronegative atom has a δ− charge, the low electronegativity atoms have a δ+ charge. As described above, the difference in polarity of two atoms is called a dipole. At this time, Dipole moment can be calculated as a vector quantity multiplied by the intensity of the two poles and the distance between the two atomic nuclei. In other words, Dipole moment can be calculated by the following equation. μ=δ*d

Each factor is the distance between: μ dipole moment/δ: magnitude of the partial charges δ⁺ and δ⁻/d: δ⁺ and δ⁻.

Our company used G09 to optimize the molecular structure with B3LYP/6-31G(d). Based on the result, Mulliken Charge value of each atom was obtained, and Dipole moment was calculated by multiplying the vector in the axial direction. Dipole moment is the vector sum of each bond dipole moment. Dipole moment value means the magnitude of the vector dipole moment, and it can be expressed as the value of the vector length as follows. |μ|=√{square root over (x ² +y ² +z ²)}

As can be seen in Table 6, when the compound of the present invention is used as the emitting layer host material, it can be seen that the efficiency is significantly improved compared to the case of using the comparative compound A or the comparative compound B.

As can be seen above, when a plurality of compounds are mixed to form the host of the emitting layer, the characteristics were different depending on the type of the first compound and the second compound, and when the same compound is applied to the second compound, it can be seen that the characteristic difference is remarkably displayed depending on the type of the first compound. Similarly, the second compound shows differences in driving voltage, efficiency, and lifespan depending on the type.

Comparing the comparative compound A and the compound of the present invention, as can be seen in Table 6, it can be confirmed that the compound of the present invention improves overall efficiency and lifespan of the element.

Table 7 is the calculated value of Dipole moment of the comparative compound A and the compound P-2 of the present invention.

TABLE 7 Comparative compound A P-2 Dipole moment 5.5878 0.4600

Comparing Comparative Compound A and the compound of the present invention, Comparative Compound A has a core in which a cyano group is further substituted with a substituent of -phenyl-naphthyl-phenyl. However, the compound of the present invention has a core that is not further substituted with a cyano group, and additionally has a substituent of -phenyl-naphthyl structure as a substituent of triazine. Due to this structure, the physical properties of the compound are changed, and in particular, as shown in Table 7, in the case of Comparative Compounds A and P-2, there is a large difference in Dipole moment. In other words, it is judged to have a high Dipole moment due to a cyano group with high electronegativity.

Due to this high Dipole moment, the charge in the molecule is biased, and the biased charge can impede the flow of charge. Therefore, it seems that the load is generated in the charge transfer and the driving voltage of the element rapidly increases, which greatly affects the efficiency and lifespan of the element.

Table 8 is data measured using the DFT Method (B3LYP/6-31g(D)) of the Gaussian program of the comparative compound A and the compound P-1 of the present invention

TABLE 8 Comparative compound A P-2 HOMO(eV) −5.866 −5.448 LUMO(eV) −1.951 −1.828 Eg(eV) 3.914 3.620 T1(eV) 2.520 2.536 S1(eV) 3.460 3.187

As can be seen in Table 8, comparing the comparative compound A and the compound P-2 of the present invention, it can be seen that T1 is similar but the energy bandgap is reduced, and in particular, that S1 is lowered. Due to this, the wavelength of the energy emitted from the host is increased, and the energy is better transferred to the red dopant. In other words, the low S1 of the compound P-2 of the present invention facilitates the transfer of Foster energy to the dopant, which appears to affect the overall performance improvement of the element.

In addition, when Comparative Compound B is compared with the compound of the present invention, it can be seen that the compound of the present invention improves overall driving voltage and efficiency of the element as shown in Table 6. Comparative compound B has a structure in which -phenyl-naphthyl is substituted with a substituent of triazine, and the compound of the present invention has a structure of -phenyl-naphthyl-phenyl. That is, it seems to affect the efficiency of the element according to the type of the substituent.

The calculated Reorganization Energy values of Comparative Compounds B and P-2 are described in Table 9.

RE values shown in Table 9 mean values calculated by RE_(elec).

TABLE 9 compound Reorganization Energy (RE) Comparative 0.299 compound B P-2 0.231

Referring to Table 9, RE value is different depending on the substituent of the triazine, the compound P-2 of the present invention has a lower RE value than the comparative compound B. That is, when having a lower RE value, it means high mobility and fast EOD, and the compound of the present invention having a fast EOD value as a whole seems to have a fast driving voltage, high efficiency, and a long lifespan. In particular, when the emitting layer is composed of a plurality of mixtures, driving, efficiency, and lifetime are determined according to the degree of ease of injection of holes and electrons into the dopant, and when the hole and electron ratio (Charge Balance) is properly maintained, the efficiency increases.

In particular, as can be seen in Examples 14 to 29, as a plurality of host compounds, the characteristics were different depending on the type of the first compound and the second compound, and in the end, it is judged that the performance of the element is determined according to the injection characteristics of holes and electrons into the dopant. In the present invention, it can be seen that through the relationship between RE value and mobility, the overall driving reduction effect, efficiency and lifespan increase effect are brought. In addition, the combination of a specific substituent substituted for triazine has a positive effect on overall mobility and acts as a hole-to-electron ratio (e.g. energy balance, stability, etc.), showing an overall improved result. That is, even within the same skeleton, RE value is determined depending on the type and substitution position of the substituent, and it can be seen that the characteristics are very different. Also, in the case of the compound of the present invention, it can be seen that the value of CIEx slightly increased, which indicates that the compound of the present invention as a host may affect the color of the element. That is, as in the present invention, when the phenanthrooxazole structure and the phenanthrene structure at a specific position are simultaneously substituted with the substituent of the triazine, the effect is considered to be maximized as a synergistic effect.
